1 Claim.

This invention relates to an extension handle for use with wrenches ofthe fixed open end and other types. It has for its main object toprovide such extension handle for use on diierent sizes and lengths ofwrenches generally known as double ended fixed jaw wrenches that areoften supplied in sets. However the handle will prove equallysatisfactory when a. longer handle is specially required on types ofsuch wrenches known as monkey wrenches and Stillson wrenches.

Further objects are to provide such a handle that will be highly eicientfor its purpose, simple in structure, cheap to manufacture= and easy touse. Other objects and advantages will appear from the drawings anddescription.

By referring to the drawings, part of this application, it will beobserved that Fig. l is a side View of the assembled handle with awrench in broken lines being held in the handle; Fig. 2 is a plan viewof Fig. l; Fig. 3 is a detail View on line 3-3 of Fig. 2 showing the endof the handle less the remainder of the handle and the wrench; Fig. 4 isa detail View on line 4-4 of Fig. 2 of the slidable member used on thehandle shown in Figs. l and 2; Fig. 5 is a side view of a modified formof the handle with a wrench in broken lines being held in the handle;Fig. 6 is a plan View of Fig. Fig. 'l is an end view on line 1 1 of Fig.5 showing part of the handle members; Fig. 8 is a side View of anothermodified form of the handle extension as used on a Stillson wrench shownin broken lines; and Fig. 9 is a plan view of Fig. S.

`Similar reference numerals refer to similar parts throughout theseveral views.

Referring to the drawings in detail it will be seen that the handlecomprises a main member l preferably made of a piece of square steelrod, bent to form a suitable handle 2 adapted for manual holding, withthe opposite end 3 formed substantially V shape and adapted to lit overthe side edge of an open end wrench 4. Mounted on the handle i is aslidable plate member 5, that may be of any desired thickness, with asubstantially V shape slot E therein that is adapted to also iit overthe side edge of the wrench 4 as shown in Figs. 1 and 2. A modified formof the handle assembly comprises an L-shaped handle member l preferablymade of square steel rod, adapted to t into a square hole 3 in a platemember 9 with integral depending ends it! provided with slots ll adaptedto fit over the side edges of an open end wrench as shown in Figs. 5 and6.

From the foregoing it will appear that in order with hollow member.

to use the handle assembly shown in Figs. 1, 2, 3 and 4 the members areheld adjacent the wrench as plainly displayed in Figs. 1 and 2. Themodified type as shown in Figs. 5, 6 and rI is used by inserting the endof the hand member into the square hole in the plate member and thenplace same rmly adjacent the wrench as plainly displayed in Figs. 5 and6.

Another modified form of the handle extension is shown in Figs. 8 and 9.This type comprises the hollow hand portion I2 with one end cut and bentoutward to form a V slot I3 integral A flat oblong bar or plate memberIll is adapted to slide snugly within the hand portion I2. This at barmember is also provided with a V l5 slot integral with its outer end.The hand portion V slot in combination with the V slot of the slidablebar member being adapted to t on the opposite sides of a regular wrenchhandle as shown in Figs. 8 and 9 to provide an extension handle thereof.

The handle parts may be made of any material suitable for the purpose,but I prefer to use steel. The invention resides in the device for itspurpose, not the material of which the parts are made. Also the handleassembly may be made in diiferent lengths and strengths of parts toaccommodate various sizes of open end and other types of wrenches.

While I have shown and described the preferred embodiment of myinvention, I do not wish to limit same to the exact and precise detailsof structure, but reserve the right to make all modications and changesso long as they remain within the scope of the following claim.

Having described my invention I claim:

In a wrench extension handle comprising: a piece of square metal rod,one end of the rod bent over itself to thus form a loop to providehandle means, the opposite end of the rod being laterally bent to form aprojection transverse to the axis of the rod and having an approximate Vshape; a ilat plate slidably mounted on said rod in confronting relationwith said V-shaped projection, said plate member being slidable betweenthe loop and projection ends of the handle, the slidable mountingconsisting of a square hole in the plate member of approximately thesame size as the square rod in order to prevent rotation of the plateabout the axis of the rod, and a V shaped slot in one edge of said iiatplate, the apeX of said V-shaped slot being inverted with respect to theapex of said V-shaped projection.
